A thermos flask is important when it comes to keeping our drinks hot or cold. Below, we are going to look at best thermos flasks in Kenya and factors to consider when buying one.

The main purpose of a thermos flask also called a vacuum flask is to maintain the temperature of the liquid in it. It achieves this through its double walled design which is separated by a vacuum. Vacuum does not transfer heat hence no heat is added or reduced from the liquid inside.

Other design features that help the flask maintain the temperature of the liquid are:

• A plastic stopper/lid, since plastic is a poor conductor of heat, no heat is lost or enters into the flask.
• A plastic exterior, applying the above mentioned property of plastic (poor conductors of heat) there is prevention of loss and entry of heat.

• A shiny exterior, if the exterior of the flask is not made of plastic, it should be of a shiny material reflecting radiation hence preventing change of temperatures.
• Above together with the vacuum between the interior and exterior wall of the flask prevent temperature change.
